AB The  abnormal  presence  of  air  in  the  pleural  cavity,  separating  the  visceral  from  the  parietal  pleura,  is  known  as  pneumothorax.  Tra­ditionally,  pneumothorax  has  been  classified  as  having  occurred  spontaneously  or  as  a  result  of  trauma.  Spontaneous  pneumothorax  can  occur  in  a  background  of  clinically  normal  lungs  (primary  spontaneous  pneumothorax  [PSP])  or  in  the  setting  of  underlying  lung  disease  (secondary  spontaneous  pneumothorax  [SSP]).  Since  underlying  anatomic  lung  abnormalities  (subpleural  blebs)  are  often  identified  in  PSP,1–3  it  is  now  believed  that  the  majority  of  PSPs  occur  in  the  setting  of  occult  lung  disease.  Nevertheless,  this  method  of  classification  is  still  common  in  practice.
